Did you know: all European ETFs are domiciled in Ireland because Ireland has a special agreement with the US where the US only withholds 15% of dividends instead of 30%?
For "Accumulating" European ETFs these dividends are automatically reinvested into the fund, so it never leaves Ireland and thus only the 15% tax is paid.
For "Distributing" European ETFs, the dividends go into investor pockets who each get taxed depending on country, usually 30% withheld by the US.

Imagine if Trump just pulled the plug on this.
